Image to WebP Converter

How to Convert Images to WebP Online

1. Upload Your Image Files: Drag and drop or click "Add Files" to select sources. 36 input formats are accepted, including JPG/JPEG/JFIF, PNG, GIF, HEIC/HEIF, AVIF, BMP, TIFF/TIF, PSD, ICO, EPS, XCF, and RAW camera formats (CR2, CR3, NEF, ARW, DNG, RW2, ORF, PEF, RAF, 3FR, X3F, MRW, DCR, ERF, MOS). Batch is supported — drop in an entire folder.
2. Choose Lossless or Lossy: Under "Lossless?", pick "No (Recommended)" for photos and most web imagery (25-34% smaller than JPEG at equivalent SSIM, per Google) or "Yes" for graphics, logos, screenshots, and any image that must be pixel-perfect (lossless WebP averages 26% smaller than PNG).
3. Set Quality and Resolution (Optional): Under "Image Compression," pick a Quality Preset (Lowest → Highest, default Very High) or switch to "Specific file size" to target a byte budget. Use Resolution Percentage, a Preset Resolution (144p–4320p), or custom Width × Height to downscale at the same time. Compression Level (1–10, default 6) and Compression Speed (1–10, default 4) trade encode time against final size.
4. Convert and Download: Click Convert. Files process on our servers and download individually or as a ZIP — no sign-up, no watermark.

Why Convert Images to WebP?

WebP is Google's open image format, first announced in September 2010 and extended in 2011 to add animation and alpha (transparency). It uses VP8 for lossy frames and VP8L for lossless frames inside a RIFF container — a single format that subsumes the jobs JPEG, PNG, and GIF used to do separately. Converting to WebP is one of the highest-ROI optimizations for any web property because the savings come from the file format itself, not from cropping or quality loss.

• Faster page loads, better Core Web Vitals — Smaller image bytes are the most direct lever on Largest Contentful Paint (LCP). Cutting hero-image weight 25-30% typically moves LCP into Google's "good" bucket without code changes.
• One format replaces three — JPG for photos, PNG for graphics with transparency, GIF for short loops. WebP handles all three: lossy + lossless + alpha + animation in a single container.
• Mobile data and storage savings — A 4 MB JPEG photo becomes ~2.7 MB WebP at the same perceived quality; a 600 KB transparent PNG logo becomes ~440 KB lossless WebP. Multiply across an image-heavy site or a phone gallery.
• Animated WebP replaces giant GIFs — Lossy animated WebP averages roughly 64% smaller than the equivalent GIF (and 19% smaller in lossless mode, per Google). It also supports 24-bit color and 8-bit alpha vs GIF's 8-bit indexed color and 1-bit alpha.
• CMS / hosting tooling expects it — WordPress 5.8+, Cloudflare Polish, Netlify Image CDN, Webflow, Shopify, and most modern static-site generators auto-serve WebP when the browser advertises support. Pre-converting your asset library skips the on-the-fly transcode tax.
• RAW and HEIC offload — Converting Canon CR2/CR3, Sony ARW, Nikon NEF, or iPhone HEIC straight to WebP yields a small, universally viewable file without round-tripping through JPEG first.

WebP vs JPEG, PNG, GIF, and AVIF

Quality Preset Quick Guide

For lossless mode, the Quality Preset slider has no effect on pixel data — it only adjusts how hard the encoder searches for compact representations. Compression Level (1–10) is the more meaningful knob in lossless mode: higher levels squeeze 5-15% more out of the file at the cost of encode time.

Frequently Asked Questions

Should I pick lossy or lossless WebP?

Lossy (the default "No" under "Lossless?") for any photographic content — JPEG-style sources, gallery uploads, social images. You'll save 25-34% versus the JPEG at SSIM-matched quality, with no visible difference at normal viewing distances. Pick lossless ("Yes") for screenshots, UI captures, logos, line art, charts, and anything where a single shifted pixel matters. Lossless WebP averages 26% smaller than the equivalent PNG and preserves every pixel exactly.

Will every browser display WebP in 2026?

Effectively yes for desktop and mobile traffic. WebP is supported in Chrome 32+, Firefox 65+, Edge 18+, Safari 16+ (partial since Safari 14 / iOS 14 / macOS Big Sur), Opera 19+, and Samsung Internet 4+. Global coverage is ~96% per caniuse. The remaining sliver is mostly legacy Internet Explorer, very old Android browsers, and some embedded WebViews — for those visitors, serve a JPEG/PNG fallback via the HTML <picture> element.

How does WebP compare to AVIF — should I just use AVIF?

AVIF compresses harder (often ~50% smaller than JPEG vs WebP's 25-34%) and supports HDR and wider color, but it encodes far more slowly and Safari only added support in version 16.4 (March 2023). The pragmatic 2026 stack is "AVIF for hero images / above-the-fold, WebP for the long tail, JPEG/PNG fallback" — served via <picture>. WebP alone covers more browsers than AVIF and converts much faster, which is why most CMS tooling still defaults to WebP.

Does WebP support transparency?

Yes — both lossy and lossless WebP carry a full 8-bit alpha channel, so soft shadows, anti-aliased edges, and partial transparency convert cleanly from PNG. You don't have to flatten to a background color the way JPEG forces you to. See PNG to WebP for the dedicated PNG path.

Can WebP replace my GIFs?

Yes, and it should. Animated WebP supports the same looping, frame durations, and disposal methods as GIF, plus 24-bit color and 8-bit alpha (vs GIF's 256-color palette and 1-bit alpha). Lossy animated WebP is roughly 64% smaller than the equivalent GIF; lossless animated WebP is around 19% smaller. See GIF to WebP for the dedicated route.

What happens to EXIF, ICC profile, and other metadata?

WebP's Extended File Format added support for EXIF, XMP, and ICC profile chunks back in October 2011. By default we preserve these on conversion, so camera metadata (date, lens, GPS) and color profiles survive the trip. If you need to strip metadata for privacy before publishing, run the WebP through a metadata-removal tool after conversion.

Why is my WebP barely smaller than the JPEG it came from?

Three common reasons. (1) The source JPEG was already heavily compressed — there's not much fat left to trim, and re-encoding at the same visual target lands at a similar size. (2) You picked the "Highest" Quality Preset, which targets archival fidelity and runs WebP at ~q95–100. Drop to "Very High" or "High" for the typical 25-34% savings. (3) You enabled lossless on a photographic source — lossless mode is for graphics, not photos. Switch "Lossless?" to "No" for photos.

Can I convert HEIC or RAW directly to WebP?

Yes — drop iPhone HEIC/HEIF, Canon CR2/CR3, Sony ARW, Nikon NEF, Adobe DNG, Panasonic RW2, Olympus ORF, Pentax PEF, Fuji RAF, and several other RAW formats straight in. The converter decodes them once and re-encodes as WebP, so you skip the JPEG round-trip that would compound losses. See HEIC to WebP for the dedicated HEIC path.

Can I go back from WebP to JPG or PNG later?

Yes. WebP is just a container — decoding it back to JPEG or PNG is straightforward and lossless from the WebP frame. Use WebP to JPG for photos or WebP to PNG when you need transparency. Note that re-encoding lossy WebP back to JPEG re-introduces JPEG quantization, so chained conversions (JPEG → WebP → JPEG) compound quality loss; archive the original.
